As a Roblox player, the current camera sensitivity feels wrong because it isn’t 1:1. In most games outside Roblox it is 1:1 and when it isn’t, players are trying to find ways to fix it.
This is happening because in the camera scripts, Y sensitivity is 25% smaller. Although this can be easily fixed, some players are used to the current behavior so this should be changeable by the user instead with two sliders, which default to (1, 0.75) to match the current behavior.
